Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling configuring the UE with a set of frequency resources and a semi-persistent resource allocation indicating a semi-persistent resource occasion on each frequency resource of the set. The UE may monitor semi-persistent resource occasions on each of the set of frequency resources for a copy of a data transmission. If the UE receives and decodes the data transmission from at least one of the semi-persistent resource occasions, the UE may transmit an acknowledgement message on a frequency resource of the set. Additionally, the UE may refrain from transmitting a feedback message on the other frequency resources of the set. If the UE does not receive and successfully decode the data transmission from any of the semi-persistent resource occasions, the UE may transmit a negative acknowledgement message on one of the set of frequency resources.
